Well constructed and attractive but not suitable for any other size cat but EXTRA SMALL! My larger cat gave it a try following his smaller sister and he peed on the edge of the tray and onto the floor. I assume the company (Meowy) that manufactured this "Loo" has gone out of business. I attempted to contact them to purchase the larger size bottom tray but no response. All in all, this was a waste of money. I didn't find that the filter tray collected anymore litter--just took away room for our kitties to do their business. I think this litter box if misrepresented on the site in that it is useless for most cats.Not happy!!
